Eadfrith

If you want to look at a molecule quickly, without starting MacroModel
type eadfrith Filename. This will display the molecule in a MacroModel file
and allow you to manipulate it. You can also render the molecule to produce pictures
suitable for publication, posters or the WWW, and display the normal modes of
a system.

The first time you run the program, you may also get a message saying that it cannot
find an Options file, so it will guess the options that you want. It will
then create an Options file, and store any changes you make to this menu.

Press RETURN immediately to display your molecule. It will appear in a new
window, and can be rotated, enlarged and moved using the mouse. A rendered
version can be made by pressing the space bar. The window can be killed by
pressing the ESC key (top left of the keyboard).

To alter the settings, type a letter, then press return. You may then be asked
for more information. The options control the picture in the following ways:

A: Alter the radius of the rendered spheres (drawn when the space bar is
pressed). 1.0 gives a ball and stick model; 4.0 gives a CPK model.

B: Controls the colouring of the rendered bonds.

C: Toggles between a new window and filling the screen with the molecule.

D: Controls the contrast in the rendered picture.

E: Controls the colour of the background. 0, 0, 0 gives a black background; 255, 255,
255 give a white background. The first number is the red component of the
colour, the second is the green component, the final number is the blue
component.

F: Decides whether to use the orientation of the previous molecule, or to use a new
orientation.

G: This option enables you to animate normal mode analyses.

H: This switches between using standard colours, or reading them from the file.

I: Turns depth cueing on or off while molecules are rotated.

J: Determines the width (in pixels) of the lines that make up the molecule.

K: This figure is the ratio of ambient to directional light in the rendered figure.
